PIPETTE TIP, PIPETTE DEVICE, PIPETTE TIP ACTUATING DEVICE AND PIPETTING METHOD IN THE NANOLITRE RANGE

摘要

The invention relates to an interchangeable pipette tip (100) comprising a first end (106) with a fluid opening (106a) and a second end (110), which has a tube (102) that is flexible in a radial direction and a mouth (112). The mouth (112) and the fluid opening (106a) have a fluidic connection. The first end (106) is configured to be coupled to a suitable coupling device (122) of a pipetting unit (120) in such a way that liquid can be sucked through the mouth (112) into the fluid region (108) by an actuating device in the pipetting unit (120). The volume of a section of the radially flexible tube is modified to eject liquid as free-flowing drops or as a jet from the mouth of the radially elastic tube.
